You can pick any organism and relate most of the cell theory to them. For instance, all living organisms are composed of cells. This is part of the cell theory and all living organisms are just that, made of cells. Another part of the cell theory that can be applied to any organism is that hereditary information is passed on from cell to cell. When we have Offspring, we pass off our hereditary information to our offspring. Lastly, part of the cell theory states that cells arise from pre-existing cells. I was born from a mother and a father so as a human I exist because I came from another human.
I think biotic but im not sure
C. Permafrost
Permafrost is the layer beneath the "active layer". The active layer consists of soil that freezes and thaws every year. However, the requirement for permafrost is that it be frozen for two or more years consecutively. This is why permafrost exists in cold environments such as tundras.
Membrane proteins can be classified into two broad categories—integral (intrinsic) and peripheral (extrinsic)—based on the nature of the membrane-protein interactions (see Figure 3-32). Most biomembranes contain both types of membrane proteins.
